Possible to add an stop valve outside the water tank?

Featured Replies

The guy who installed our water tank with connected pump years ago didnt fit the stop valve inside the tank..Q: can i add a normal ball valve on the pipe between the tank and the pump,or it wouldnt work? Idea is to fill up the water in the evening with the valve closed,and then open it in the morning for use...like now the water thats left in the tank at the end of the day is gone in the morning...and we have slow water supply..

Install a ball valve on the house supply line from that tank ?
Theres no reason you can't.

Perfect.

Why not find the leak ?
Check the toilets first, turn them all off at the wall. Check the tank in the morning, if theres still water, its not the toilets but if the waters gone...............
Toilets can leak and you'd never know.

Sounds like you need a non-return valve (check valve) on the line which supplies your tank. So that the water can't return to the supply.

If the rest of the community is sucking the water from your tank, you need to install a check valve, not a ball valve.

the check valve will allow water to flow into the tank, but stop the water from flowing from the tank back into the community.

Exactly, and everyone should have these regardless. I think you have to have them by law.

The more valves the easier to locate any leaks. Toilets is a common one as you say in another post. Needs constant service because of the hard water here.

Actually we have a toilet leak also..when we flush the water from the toilet sometimes it spill out(just a little bit) on the outside from the latrin tank,what could be the problem?

Same thing happens to me. My tank has the inlet at the top from the well pump, and the outlet to the house pump. I would fill the tank and it would be almost empty in a day. I'm guessing your water is leaking out back into the supply line from your tank as the inlet is at the bottom?

One toilet not used and turned off waiting on inner replacement. the other no obvious leak but my one sink was leaking inside the wall. A man came out recently and fixed that leak.

One other thing. I would hear the house pump cycling for a second or two, which meant I did have that leak. Now it doesn't cycle after the wall leak was fixed, but the tank still lowers daily. The only way it doesn't is if the tank valve between the tank and house pump (what you want to install) is turned off. Very strange, as i don't see anywhere the water is going like it did with the wall leak from the bathroom sink. Before I noticed the sink wall leak, i thought the water was leaking out from the PVC pipe under the house, which is still might be.

Alternative routing idea: deliver incoming water through the top of the tank and add a ball valve with floats and a switch at the top to control the pump & so prevent the tank from overfilling. AFAIU that would prevent water returning to your Moo independently of calced up valves, etc.

We have our own well that pumps off-the-scale-hard water from God alone knows how deep to the top of a large container 9m + height of the bottle above ground. We have floats and a switch to control the pump flow.

Under the toilet tank is a seal which needs replacement occasionally. I have the same thing, which is what I'm fixing next in the toilet that's turned off. Easy to replace .............https://www.korky.com/toilet-repair-help/how-to-fix-leak-between-toilet-tank-and-bowl

Incoming water is at the top of the tank,outgoing at the bottom.

There is a rubber seal in the bottom of the tank and they can leak from there BUT they typically will leak because the float doesn't shut off all the way.

From your picture, absolutely put a SS ball valve there.

If you are thinking of cutting the pipe to instal something you need to but. Do this.

Although depending on the water pump most, say Mitsubishi-type, pumps have an integral non-return valve. It is a plastic widget with a top mounted spring. Usually the spring is corroded.

You can by a new widget and spring at local mom and pop water pump shops.
